SN74AS161DR Overview


A device of this type is supplied in a package of type [0]. Using 16terminations, it can be configured. By supplying 5Vwith a voltage of 5V , the device can be operated in a completely flexible manner. An interconnection of 1elements is provided by wires. A total of 16pins are present on all components. As a result, it is packaged as Tape & Reel (TR). Initially, it appears to belong to the AS family. As a member of the 74ASseries, it is ideal for a wide range of applications. Binary Counteris used as the logic type. Setting the operating temperature to 0°C~70°C is recommended. Mounting type Surface Mountis used. In the case of a supply voltage of [0], it operates more reliably. The array consists of elements storing 4bits each. The result may be yeswhen expressing the result in Pbfree code. Among the features of this electronic device, TCO OUTPUTare essential. It is possible to supply voltages up to 5.5V volts (Vsup).
